I just looked at span-dynamic-performer.cc to see how it works. If I understand this correctly, it will announce a new Audio_dynamic item after the start of a dynamic-span for each moment in which an event occurs. Is this correct? My only problem with this is the following: It doesn't appear to allow a crescendo to happen throught a single note without some extra hackery added. It would be better (IMHO) if we could emit Audio_dynamic events (or Audio_tempo events) at discrete quantum intervals. It doesn't seem possible, however, to emit Audio_items at any moments other than those defined in the Music proper. Suggestions? Maybe Audio_staff::audio_items_ can be a priority queue (by moment), allowing us to emit events out of order? -- Michael Welsh Duggan ([EMAIL PROTECTED]) _______________________________________________ lilypond-devel mailing list lilypond-devel@gnu.org http://lists.gnu.org/mailman/listinfo/lilypond-devel
